okay, but I make it 42 hours per week. Are you on a salary, independent of the number of hours you work? If so, then you might try harder to make your own schedule. If not, then you might try harder to make sure that they pay you time and a half for the extra hours.
No, I get paid hourly. And yes if I ever work overtime, I do get paid time and a half.
I should point out my job also pays a shift differential for working late and weekends, so even if a Monday, Tuesday, Thursday and Friday schedule was available, I would get paid less for it.
